Description

intThe number of components on the GameObject as an Integer value.

Remarks

You can use 
GetComponentCount
to iterate through component indices, which is especially convenient if used together with GameObject.GetComponentAtIndex. For example, you can iterate through the indices to find the index of a particular component you're interested in and then save the index for later use.
using UnityEngine;public class IterateComponents : MonoBehaviour{int m_SavedComponentIndex = -1;    void Start()    {        //Iterate through components  on the GameObject        for (int i = 0; i < gameObject.GetComponentCount(); i++)        {            var currComponent = gameObject.GetComponentAtIndex(i);            //Check if it is a Rigidbody component            if (currComponent.GetType() == typeof(Rigidbody) )            {                m_SavedComponentIndex = i;            }        }        Debug.Log(m_SavedComponentIndex != -1 ? $"Found component at index: {m_SavedComponentIndex}" : "Could not find component");    }}
